WlRE-BENDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 707,006, dated August 12, 1902.

Application filed Matt 17, 1902.

To aZZ whom, it may concern:

Be itknown that we, GEORGE F. PROSS and ANDREW P. TUCKER, of Cincinnati, in the. county of Hamilton and State of Ohio, have invented certain new and useful Improvements in VVire-Bending Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Our invention relates to an improvement in wire-bending machines, the object of the invention being to provide a machine of this character which will automatically bend at right angles both ends of Wires continuously fed thereto, and so construct the machine as to permit the attendant at all times to View the feeding and bending operation, and, further,to provide a wire-bending machine which will be extremely simple in construction and strong and durable when in operation.

With these objects in View the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fnllyhereinafter described, and pointed out inthe claims.

In the accompanying drawings, Figure 1 is a plan View illustrating our'improvements. Fig. 2 is a side view of the machine. Fig. 3 is a View in section on the line a; x of Fig. l.

j usted to bend short wires. Fig. 5 is a'view in section at right angles to Fig. 3, and Figs. 6 and 7 are enlarged views illustrating details of construction.

1 represents a bed-plate, preferably supported on legs 2, secured to the. floor, and for convenience a tool-tray 3 is supported on the legs below the bed-plate.

Near one end of the bed-plate 1 and at opposite sides thereof standards 4 are secured by bolts 5, as shown, and in these standards and projecting beyond the same at both ends a shaft 6 is mounted to revolve. This shaft 6 is made with a longitudinal groove or keyway 7, and corresponding grooves or keyways are provided in' disks or cylinders 8, mounted on the shaft for the reception of keys 9 to lock the disks and shaft together. The intermediate disks 8 are preferably made with Serial No. 98,647. (No model.)

hubs having set-screws therein to lock the keys in position, while the end disks are made wider than the intermediate disks and have their adjusting set-screw in the body of the disks, as clearly shown in Fig. 7. As many of these disks or cylinders may be provided as desired, four being shown in the drawings; but more or less than four may be employed, as is found most desirable.

All of the disks or cylinders 8 are provided in their peripheries with alined notches or pockets 10 to receive wire blanks 11, fed there* to, as will now be explained.

Connecting the upperends of standards 5 are cross-bars 12, having inclined parallel edges and spaced apart, as shown, and between these bars 12 the lower ends of guidestripsj13 project. These guide-strips 13 are disposed parallel and just the proper distance apart to permit the free passage of the wires between them, and the series of guide strips 13 are connected by bars 14, the lower guide-strips of the series being longer than the upper strips to support an inclined tray or platform 16, while the upper strips have securedat their ends inclined tongues 17 to guide the wires between the strips. Between the guide-strips at the sides of the machine guide-barslS are secured by pins 19, the bar 18 at one side of the machine being adjustable in the guide-strips to accommodate various lengths of wires to be bent, and to the upper ends of these bars 18 wings 20 are secured and project over tray or platform 16 and constitute, in effect, a hopper to guide the wires into the guide-strips, down which they pass to the disks or cylinders 8, and suitable brace rods 21 are preferably provided to strengthen this hopper, as clearly shown in Fig. 5.

A series of ribbed concaves 22 are secured to the forward cross-bar 12 and bed-plate 1, three of said concaves being provided, aconcave located in close proximity to the end disks or cylinders 8 and one concave located at a suitable point between the end concaves and adapted to hold the wires in the pockets of the disks or cylinders and prevent their escape until the ends of the wires are bent. To

the bed-plate 1, at the rear of slot 23 therein,

eject the bent wires from the pockets if they should stick therein.

To bend the ends of the wires, which, it will be seen, project beyond the end disks 8, an abutment 25, which is preferably a roller, is provided in the path of the-ends of the wires, and these rollersare mountedon removable pintles 27 and between parallel ears 28 on brackets 26, secured to standards 4, andare adapted to be struck by the protruding ends of the wires, and as the disks are rotated, carrying with them the main portion of the wires, the ends will be bent upward at right angles and against the end disks 8 before they will be free to pass the rollers 25, thus effectually bending both ends of thewires at right angles before they are ejected from the disks.

The rollers are preferably composed of' hardened steel to withstand the wear there r on, and to prevent wear of the end disks where the great bending strain is applied a series of removable hard-metal blocks 29 are secured in correspondingly-shaped recesses in enddisks Sat the notches or pockets therein, and these blocks are preferably grooved in one side, as shown at 30, to permita certain amount of play of the ends of the wires during the bending'operation, and it will be seen that these blocks can be removed when worn and replaced by new blocks.

Gear-wheels 31 are secured on shaft 6 atits ends and mesh with chains of gearing 32, operated by drive-shaft 33, on which latter a drive-pulley 34: is mounted at the center of bed-plate 1 and connected bya belt 34 with any suitable power.

On drive-shaft 33 and on a short shaft 35, carrying agear-wheel of one chain of gear- .ing, largeand small gears 36 and 37 are provided and intermesh, the gears on said shafts being of relatively the same size, the smaller gears meshing with the larger gears and serve to steady the machine.

While we might of course apply power directly to shaft 6, still we prefer to employ chains of gearing, as shown, to steady the machine and compensate for the shock of the wires coming. in contact with the rollerabutments 25. i

b When it is desired to bend shorter wires than those for which the machine is set in Figs. 1 and 3, the standard. 4. at one side of the machine is released and moved toward the center of the machine, as shown in Fig. 4, and secured in such position by the bolts 5, used for its attachment in the former position. The disks or cylinders 8 are of course moved toward each other, and an additional bearing 38 is secured in place to support the protruding end of shaft 6.- An additional guide 39 is now secured at the proper position between cross-bars 14, and the machine is ready to bend wires of short length. The

to /30cc machine maybe permitted a great many such adjustments, and suitable oil-cups 40 are provided for lubricating the various bearings of the machine. I p v The operation of our improvements is as follows: The wire blanks 11 are fed to the tray or hopper 16 and pass down in single file through the guide-strips 13, from which they fall into the pockets 10 of the revolving disks or cylinders Sand are held in said pockets by concaves 22 until. the ends of the wires are bent by being brought into contact with roller 25and reach a position to be dropped down through the opening in bed-plate 1. The attendant cansee the wires at allftimes, and if anything should happen to affect the perfectoperation' of the machine or if the de artin from our invention and hence we h 3 donot wish to be limited to the precise construction set forth, but consider ourselves at liberty to make such slight changes and alterati'ons as fairly fall within the spirit and scope of our invention.
